摘要： The present invention provides a method for decreasing the Conradson carbon ("Concarbon") number of petroleum feedstreams by passing an electric current through a mixture of a petroleum stream, typically having a Conradson carbon residue of at least about 0.1% and an aqueous electrolysis medium at a pH and cathodic voltage for a time sufficient to decrease the Conradson carbon number of the petroleum stream. The electrolysis medium contains quaternary carbyl or hydrocarbyl onium salts; inorganic hydroxides such as NaOH or KOH, or mixtures thereof. A cathodic voltage of 0 V to -3.0 V vs. Saturated Calomel Electrode (SCE) and a pH of 6-14, preferably 7 to 14, more preferably above 7 to 14 are used.The invention has utility for converting less economically desirable refinery feeds to feeds that are more valuable.

摘要： A process for hydrocracking a hydrocarbon feedstock having a propensity to form polynuclear aromatic hydrocarbon compounds to suppress fouling the processing unit. The hydrocracking method includes contacting the hydrocarbon feedstock with a crystalline zeolite hydrocracking catalyst, contacting at least a portion of the resulting unconverted hydrocarbon oil containing polynuclear aromatic compounds with an iron catalyst in the presence of hydrogen to hydrogenate and hydrocrack the polynuclear aromatic hydrocarbon compounds, and recycling unconverted hydrocarbon oil having a reduced concentration of polynuclear aromatic compounds to the hydrocracking zone.

摘要： A process wherein a feed comprising an admixture of liquid hydrocarbon compounds which includes a polynuclear aromatic hydrocarbon compound, or compounds (PNA's) is contacted in the presence of hydrogen over an iron catalyst at temperature sufficient to selectively hydrogenate and hydrocrack, or destroy the PNA's of the admixture without excessively hydrogenating and hydrocracking the non-PNA's of said feed. The process is particularly applicable for the removal of PNA's from reformates, processed naphthas, and other hydroprocessed streams or the like to achieve a lower and more favorable distribution of PNA's in a motor gasoline pool, and further to remove PNA's from prime fuels and heavier hydrocarbon mixtures.

摘要： A process for the production of high octane gasoline, or high octane gasoline blending components, from a sulfur-containing feed rich in fused two-ring aromatic hydrocarbons, inclusive of naphthalenes. The feed is hydrogenated in a first reaction zone to desulfurize the feed and saturate one ring of the fused two-ring aromatic hydrocarbons, but insufficient to saturate the second ring of said molecular species, to form tetralins. The product, as a feed, is reacted in a second reaction zone over a catalyst comprised of elemental iron and one or more alkali or alkaline-earth metals components to selectively hydrogenate and crack the previously hydrogenated fused two-ring aromatic hydrocarbons to produce lower molecular weight higher octane components suitable per se as gasoline, or gasoline blending components. The feed rich in fused two-ring aromatic hydrocarbons can be split from a wider boiling range hydrocarbon to obtain, additionally, a component rich in fused multi-ring aromatic hydrocarbons having three or more rings to the molecule, which fraction can also be hydrogenated to produce other fuels, or raw materials feed components.

摘要： A process for the production of high octane gasoline, or high octane gasoline blending components from a sulfur and nitrogen-containing feed composition of wide boiling range rich in fused multi-ring aromatic hydrocarbons containing two, and three or more rings in the molecule. The feed is first hydrogenated to desulfurize, denitrogenate and saturate one ring of the two-ring molecular species, but insufficient to saturate the second ring of said molecular species. The product, as a feed, is then hydrocracked to crack fused multi-ring aromatic hydrocarbons containing three or more rings to the molecule, and to produce lower molecular weight, lower boiling components. The product of the hydrocracker is then split into blends which include (i) a blend rich in fused two-ring aromatic hydrocarbons and (ii) a blend rich in fused multi-ring aromatic hydrocarbons containing three or more rings to the molecule. Blend (i) is selectively hydrogenated and cracked over a catalyst comprised of elemental iron and one or more alkali or alkaline-earth metals to produce gasoline or gasoline blending components, and blend (ii) is hydrocracked to produce gasoline or gasoline blending components.

摘要： A process wherein in a hydrofining zone, a sulfur- or nitrogen-containing distillate feed, or feed containing both sulfur and nitrogen, is hydrofined at hydrofining conditions sufficient to convert the sulfur and nitrogen to hydrogen sulfide, and ammonia, respectively, the hydrogen sulfide and ammonia are separated from the hydrofined product, and the hydrofined product contacted in a subsequent zone with hydrogen, or a hydrogen-containing gas over a catalyst which contains elemental iron and one or more alkali- or alkaline-earth metals at reaction conditions sufficient to reduce or restore the color of the hydrofined product. Operation in this manner permits hydrofining of the feed at higher severities, for longer periods, than heretofore possible because the adverse quality of the product reaction mixture normally caused by deterioration of the hydrofiner product at such conditions is remediated by treatment of the hydrofined product over the iron catalyst.
